Preparation of Syngas via Catalytic Gasification of Biomass with a Nickel-based Catalyst

摘要

Biomass gasification to produce syngas was carried out in a fluidized bed reactor and a catalytic fixed bed reactor. The feedstock was sawdust and the cracking catalyst included the calcined dolomite, Ni/dolomite, Ni/modified dolomite, and reforming catalyst. The Ni/modified dolomite catalyst showed better performance and low cost. The optimum technological conditions were as follows: fluidized bed temperature, 1,073 K; catalytic fixed bed temperature, 1,073 K; the mass ratio of steam to biomass, 2.0.
